BACKGROUND

In load control systems, standard mechanical switches (e.g., decoratorpaddle switches, etc.) may be replaced with more advanced load controldevices, such as dimmer switches, that control the amount of powerdelivered from an alternating-current (AC) power source to an electricalload. This procedure typically requires that the old decorator paddleswitch be un-wired and removed from the load control system and the newload control device to be connected to the electrical wiring. Typically,such a procedure must be performed by an electrical contractor or otherskilled installer. The average consumer may not feel comfortable tocomplete the installation of the load control device. Accordingly, thereis a need for a load control system that may be installed in an existinginstallation having a decorator paddle switch without requiring anyelectrical work, and that is aesthetically pleasing.

SUMMARY

As described herein, a remote control device for use in a load controlsystem, for example to control electrical loads and/or load controldevices, may be configured to be mounted over an installed mechanicalswitch having a paddle actuator. The mechanical switch may controlwhether power is delivered to an electrical load. The remote controldevice may be installed without accessing electrical wiring of themechanical switch.

The remote control may include a base and a control unit that isconfigured to be removably attached to the base. The control unit mayinclude a control interface and a wireless communication circuit. Thecontrol unit may translate a user input received at the controlinterface into a control signal that controls a load control device. Thecontrol unit may cause the wireless communication circuit to transmitthe control signal.

The base may include a mounting tab and a frame. The mounting tab may beconfigured to be attached to a protruding portion of the paddle actuatorof the mechanical switch. For example, the mounting tab may define anattachment surface that is configured to be secured to the paddleactuator, for example using a double-sided adhesive. The frame maydefine an opening that is configured to receive the protruding portionof the paddle actuator therein. The frame may be configured to allowattachment of the control unit to the frame. The frame may be configuredto receive a battery for powering the control unit, and may include aprinted circuit board that is configured to electrically couple thecontrol unit to the battery when the control unit is attached to theframe.

When the remote control device is mounted over the mechanical switch,the base may cause a rear surface of the frame to be biased against astructure of the mechanical switch, such as the bezel that surrounds thepaddle actuator or the faceplate of the mechanical switch. The base mayinclude one or more alignment members that extends from the rear surfaceof the frame. The alignment members may be configured to be received ina gap that is defined between the bezel and the opening of thefaceplate.

In an example implementation of the base, the mounting tab may bemonolithic with the frame, and may define an attachment surface that isangularly offset relative to the rear surface of the frame. The framemay include an outer wall that extends along a perimeter of the frame,and a cross member that extends between opposed side walls of theperimeter wall. The mounting tab may extend outward from a fixed endthat is supported by the cross member, to a free end.

In another example implementation of the base, the base may furtherinclude a resilient attachment member that extends from the frame andthat is configured to engage with the mounting tab. The mounting tab maybe configured to receive and captively retain the attachment member. Theattachment member may include a first portion that is supported by theframe and a second portion that defines a tab that extends outward fromthe first portion. The mounting tab may define a channel that isconfigured to receive the tab. The frame and the attachment member maybe configured such that the attachment member is held in a fixed inposition when supported by the frame.

In another example implementation of the base, the base may furtherinclude a resilient attachment member that extends from the frame andthat is configured to engage with the mounting tab. The mounting tab maybe configured to receive and captively retain the attachment member. Theattachment member may include a first portion that is supported by theframe and a second portion that defines a tab that extends outward fromthe first portion. The mounting tab may define a channel that isconfigured to receive the tab. The frame and the attachment member mayconfigured such that the attachment member is translatable relative tothe frame when supported by the frame.

DETAILED DESCRIPTION

FIGS. 1-5 depict an example remote control device 100 that may beinstalled in a load control system, such as a lighting control system.The load control system may include a mechanical switch, such as theillustrated mechanical switch 190, that may be in place prior toinstallation of the remote control device 100, for example pre-existingin the load control system. As shown, the mechanical switch 190 may be astandard decorator paddle switch. The load control system may furtherinclude one or more electrical loads, such as lighting loads. Themechanical switch 190 may be coupled in series electrical connectionbetween an alternating current (AC) power source and the one or moreelectrical loads (not shown).

The mechanical switch 190 may include a paddle actuator 192 that may beactuated to turn on and/or turn off, the one or more electrical loads.The mechanical switch 190 may include a bezel 194 that surrounds thepaddle actuator 192. The mechanical switch 190 may include a yoke (notshown) that enables mounting of the mechanical switch 190 to astructure. For example, the yoke of the illustrated mechanical switch190 may be fastened to a single-gang wallbox that is installed in anopening of a wall. As shown, a faceplate 196 may be secured to themechanical switch 190, for instance to the yoke. The faceplate 196 maydefine an opening 198 that extends therethrough. The opening 198 may besized to receive the bezel 194 therein, such that a narrow gap 197 isdefined between the bezel 194 and the opening 198 around the perimeterof the bezel 194. As shown, with the faceplate 196 secured to themechanical switch 190, the bezel 194 may protrude beyond an outersurface 199 of the faceplate 196. The outer surface 199 of the faceplate196 may alternatively be referred to as a front surface of the faceplate196.

In accordance with the illustrated orientation of the mechanical switch190, an upper portion of the paddle actuator 192 may define a firstactuation surface 191 that may be pressed to operate the paddle actuator192 into a first position (e.g., as shown in FIG. 2A) from a secondposition, and a lower portion of the paddle actuator 192 may define asecond actuation surface 193 that may be pressed to operate the paddleactuator 192 from the first position into the second position. As shown,the first position of the paddle actuator 192 may correspond to an “on”position of the mechanical switch 190, which corresponds to themechanical switch 190 allowing power from the AC power source to bedelivered to the one or more electrical loads. With the paddle actuator192 in the first, or “on” position, the lower portion of the paddleactuator 192 may project outward relative to the bezel 194 and thefaceplate 196, and may be referred to as a protruding portion of thepaddle actuator 192. It should be appreciated that in an alternativeconfiguration in which the second position of the paddle actuator 192corresponds to the “on” position of the mechanical switch 190, the upperportion of the paddle actuator 192 may project outward relative to thebezel 194 and the faceplate 196, and thus may be referred to as theprotruding portion of the paddle actuator 192.

The load control system may further include a load control device (notshown) that is electrically connected to the one or more electricalloads. The load control device may include a load control circuit forcontrolling the intensity of one or more of the electrical loads betweena low end intensity (e.g., approximately 1%) and a high-end intensity(e.g., approximately 100%), and may include a wireless communicationcircuit. In an example implementation, the load control device may be astandalone dimmer switch that is electrically connected to the one ormore electrical loads. In another example implementation, each of theone more electrical loads may be a controllable light source (e.g., ascrew-in light-emitting diode (LED) lamp) that each may include arespective integrated load control circuit and wireless communicationcircuit (e.g., the electrical load includes a corresponding load controldevice that is configured for wireless communication). It should beappreciated that the load control system is not limited to the exampleload control devices described herein.

As shown, the example remote control device 100 may include a controlunit 110 and a base 120 that may operate as a mount for the control unit110. The base 120 may alternatively be referred to as a base portion ora mounting assembly. The control unit 110 and the base 120 may beconfigured such that the control unit 110 may be removably attached tothe base 120. The base 120 may be attached to the paddle actuator 192 ofthe mechanical switch 190 without removing the faceplate 196. In thisregard, the remote control device 100 may be mounted over an installedmechanical switch, such as the mechanical switch 190, without performingany electrical re-wiring of the mechanical switch 190.

As shown, the base 120 may include a mounting tab 130 and a frame 150.The mounting tab 130 may be configured to be attached to the protrudingportion of the paddle actuator 192 of the mechanical switch 190. Forexample, as shown the mounting tab 130 may have a rectangular-shapedbody that defines an attachment surface 132 that is configured to besecured (e.g., adhered) to the protruding portion of the paddle actuator192. The attachment surface 132 may be adhered, for example, usingdouble-sided adhesive such as the illustrated sheet 145 of double-sidedadhesive as shown in FIG. 2A. The mounting tab 130 may be made of anysuitable material, such as plastic. It should be appreciated thatattachment of the mounting tab 130 to the paddle actuator 192 is notlimited to double-sided adhesive, and that the mounting tab 130 may bealternatively configured to otherwise attach to the protruding portionof the paddle actuator 192, for example mechanically (e.g., using one ormore fasteners).

As shown, the frame 150 may include an outer wall 152 that extends alonga perimeter of the frame 150. The outer wall 152 may alternatively bereferred to as a perimeter wall of the frame 150. The outer wall 152 mayinclude a first end wall 154, an opposed second end wall 156, andopposed side walls 158 that extend from respective ends of the first endwall 154 to corresponding ends of the second end wall 156. In accordancewith the illustrated orientation of the frame 150, the first end wall154 may be referred to as an upper end wall of the frame 150 and thesecond end wall 156 may be referred to as a lower end wall of the frame150. The outer wall 152 may define a rear surface 160 of the frame 150.

In accordance with the illustrated configuration of the frame 150, theframe 150 may be configured such that the outer wall 152 encloses anddoes not interfere with the bezel 194 when the frame 150 is placed overthe bezel 194, and such that the rear surface 160 of the frame 150 abutsthe outer surface 199 of the faceplate 196. It should be appreciatedthat the outer wall 152 of the frame 150 is not limited to theillustrated geometry. For example, the frame 150 may be alternativelyconfigured such that the outer wall 152 (e.g., at least a portion of therear surface 160 of the frame 150) abuts the bezel 194 when the base 120is attached to the protruding portion of the paddle actuator 192. Inanother example, the frame 150 may be alternatively configured such thatthe outer wall 152 encloses the faceplate 196 of the mechanical switch190, for instance such that the rear surface 160 of frame 250 abuts asurface of a structure in which the mechanical switch 190 is installed,such as a surface of a wall.

The frame 150 may further include a cross member 162 that extendsbetween the opposed side walls 158 of the outer wall 152 (e.g., from afirst one of the side walls 158 to the other side wall 158). The frame150 may define an opening 164 that extends therethrough. The opening 164may be configured to receive the protruding portion of the paddleactuator 192 therein. When the protruding portion of the paddle actuator192 is received in the opening 164, the frame 150 may at least partiallysurround the paddle actuator 192 (e.g., as shown in FIG. 3). The frame150 may be made of any suitable material, such as plastic.

The base 120 may further include an attachment member 166 that may beconfigured to engage with the mounting tab 130 so as to secure the frame150 to the mounting tab 130. The attachment member 166 may include afirst portion 165 that is configured to be attached to the frame 150.For example, as shown the first portion 165 of the attachment member 166may be configured to be attached to the cross member 162 and the opposedside walls 158 of the frame 150. In accordance with the illustratedconfiguration of the frame 150, the first portion 165 of the attachmentmember 166 may be supported by the frame 150 such that the first portion165 is fixed in position relative to the frame 150. The attachmentmember 166 may further include a second portion 167 that defines a tab168 that extends outward from the first portion 165. In this regard, theattachment member 166 may extend from the frame 150. The attachmentmember 166 may be a resilient attachment member. For example, theattachment member 166 may be made of a suitably resilient material, suchas metal.

The mounting tab 130 may be configured to receive and captively retainthe attachment member 166. For example, as shown the mounting tab 130may define a channel 134 that is configured to receive the tab 168 ofthe attachment member 166 therein. In accordance with the illustratedconfiguration of the mounting tab 130, the mounting tab 130 may includea pair of opposed ledges 136 that define the channel 134. The ledges 136may be configured such that the channel 134 is wider than a width of thetab 168. This may allow lateral (e.g., side-to-side) movement of theframe 150 when the tab 168 is received in the channel 134, which may inturn allow alignment of the base 120 relative to the mechanical switch190, for instance via one or more optional alignment members (not shown)that may protrude from the frame 150 and that may be configured to bereceived in the gap 197 between the bezel 194 and the opening 198 of thefaceplate 196.

The mounting tab 130 and the frame 150 may be configured to, when thebase 120 is attached to the paddle actuator 192 of the mechanical switch190, cause the rear surface 160 of the frame 150 to be biased against astructure that surrounds the paddle actuator 192, such as the bezel 194or the outer surface 199 of the faceplate 196. As shown (e.g., in FIG.2A), the second actuation surface 193 of the protruding portion of thepaddle actuator 192 may form a first angle α1 relative to the bezel 194of the mechanical switch 190, and the tab 168 may extend from the firstportion 165 of the attachment member 166 at a second angle α2 relativeto the rear surface 160 of the frame 150. The second angle α2 may besmaller than the first angle α1.

The mounting tab 130 may be configured such that when the tab 168 isdisposed into the channel 134, the ledges 136 may bias the tab 168against an outer surface 133 of the mounting tab 130. Accordingly, whenthe mounting tab 130 is attached to the protruding portion of the paddleactuator 192 and the tab 168 is received in the channel 134, the tab 168may deflect due to the size difference between the second angle α2 andthe first angle α1. This deflection of the tab 168 may cause the firstportion 165 of the attachment member 166 to be biased rearward, therebycausing the rear surface 160 of the frame 150 to be biased against theouter surface 199 of the faceplate 196. This may minimize, or eliminate,gapping between the rear surface 160 of the frame 150 and the outersurface 199 of the faceplate 196.

The base 120 and the control unit 110 may be configured to enablereleasable attachment of the control unit 110 to the base 120. Forexample, one or more components of the base 120 may include engagementfeatures that may be configured to engage with complementary engagementfeatures of the control unit 110. As shown, the attachment member 166may define a pair of resilient clips 170 that may be configured toengage with complementary engagement features (not shown) defined oncorresponding inner surfaces of the control unit 110. In this regard,the frame 150 may be configured for releasable attachment of the controlunit 110 to the frame 150, via the attachment member 166.

The control unit 110 may define a control interface that is configuredto receive inputs, such as finger presses and/or gestures, from a userof the remote control device 100. For example, in accordance with theillustrated configuration, the control unit 110 may be configured topivot about a central axis, when attached to the base 120, in responseto actuations of respective upper and lower portions 112, 114 of thecontrol unit 110. The control unit 110 may further define a capacitivetouch surface along the upper and lower portions 112, 114, that may beconfigured to detect touches along an x axis, a y axis, or both an x andy axis.

The control unit 110 may include a control circuit (not shown) and awireless communication circuit (not shown). The control unit 110 may beconfigured to translate one or more inputs (e.g., user inputs) from thecontrol interface into respective control signals that may be used tocontrol a load control device of a load control system. The one or moreinputs may be applied via touches or presses of the upper portion 112and/or lower portion 114 of the control unit 110. For example, thecontrol circuit may be configured to receive input signals (e.g., thatcorrespond to the user inputs) in response to actuations of the upperportion 112 and/or lower portion 114 by a user of the remote controldevice 100. For example, the input signals received by the controlcircuit may be the respective control signals translated from thecontrol interface inputs. The control circuit may be configured togenerate commands that the user desires the control unit 110 to executein response to the input signals produced in response to actuations ofthe upper portion 112 and/or lower portion 114. The control unit 110 maybe configured to cause the wireless communication circuit to transmitone or more control signals including the commands generated by thecontrol circuit.

The control unit 110 may be configured to provide a visual indicationassociated with inputs and/or gestures received by the upper portion 112and/or lower portion 114. For example, the control unit 110 may furtherinclude a plurality of light emitting diodes (LEDs) (not shown) that areconfigured to provide the visual indication. In accordance with theillustrated control unit 110, the plurality of LEDs in a linear arraythat extends between the upper and lower ends of the control unit 110.The control unit 110 may include a light bar 116 that may be configuredto allow light, for instance from one or more of the LEDs, to be emittedoutward from an interior of the control unit 110. For example, the lightbar 116 may comprise a light pipe that is disposed in a slot thatextends into an outer surface of the control unit 110 (e.g., through abody of the control unit). In another example, a body of the controlunit 110 may be made of a translucent material that may be coated withan opaque material (e.g., an opaque paint) and an opening for lightemitted from the light bar 116 may be defined by removing acorresponding portion of the opaque material. It should be appreciatedthat the control unit 110 is not limited to the illustrated geometry ofthe light bar 116.

The control circuit may be configured to cause the wirelesscommunication circuit to transmit respective commands that correspond toinputs and/or gestures received by the upper portion 112 and/or lowerportion 114. For example, the remote control device 100 may be operableto transmit wireless signals, for example radio frequency (RF) signals,to a load control device, one or more electrical loads, and/or a centralprocessor of a load control system. The remote control device 100 may beassociated with the load control device and the one or more electricalloads during a configuration procedure of the load control system.

The control unit 110 may be battery-powered. The frame 150 may beconfigured to receive a battery 185 for powering the control unit 110.The remote control device 100 may optionally include the battery 185. Asshown, the first portion 165 of the attachment member 166 and the crossmember 162 may define a cradle 172 configured to receive the battery185. The first portion 165 of the attachment member 166 may define apair of positive battery contacts 174. The base 120 may be configured toprovide power from the battery 185 to the control unit 110 when thecontrol unit 110 is attached to the base 120. For example, the base 120may include a battery printed circuit board (PCB) 180 that may bemounted to the frame 150 (e.g., to posts that protrude from the crossmember 162). As shown, the battery PCB 180 may define a front side 181and an opposed rear side 183. The battery PCB 180 may include a negativebattery contact (not shown) mounted to the rear side 183, and that maymake contact with the battery 185 when the battery PCB 180 is attachedto the frame 150. The battery PCB 180 may also include a circuit commoncontact 184 and a supply voltage contact 186 mounted to the front side181 of the battery PCB 180.

The control unit 110 may be configured such that power may betransferred from the battery 185 to the control unit 110 via the circuitcommon contact 184 and the supply voltage contact 186, regardless ofwhether the base 120 is attached to the paddle actuator 192 of themechanical switch 190 with the paddle actuator 192 in the first position(e.g., as shown in FIG. 2A) or in the second position. For example, thecontrol unit 110 may include a control PCB 175 that includes a centrallylocated circuit common electrical pad 176, and a pair of supply voltageelectrical pads 177A, 177B that flank the circuit common electrical pad176, for example, as shown in FIG. 2B. In accordance with such aconfiguration of the control PCB 175 of the control unit 110, when thecontrol unit 110 is attached to the frame 150 in a first orientation(e.g., when the paddle actuator 192 is in the first position), thecircuit common contact 184 of the battery PCB 180 makes contact with thecircuit common electrical pad 176 of the control PCB 175 of the controlunit 110, and the supply voltage contact 186 of the battery PCB 180makes contact with a first supply voltage electrical pad 177A of thecontrol PCB 175 of the control unit 110 (e.g., but not a second supplyvoltage electrical pads 177B). When the control unit 110 is attached tothe frame 150 in a second orientation (e.g., 180 degrees flipped fromthe first orientation and when the paddle actuator 192 is in the secondposition), the circuit common contact 184 of the battery PCB 180 makescontact with the circuit common electrical pad 176 of the control PCB175 of the control unit 110, and the supply voltage contact 186 of thebattery PCB 180 makes contact with the second supply voltage electricalpad 177B of the control PCB 175 of the control unit 110 (e.g., but notthe first supply voltage electrical pads 177A). In this regard, thebattery PCB 180 of the base 120 may be configured to, when the controlunit 110 is attached to the frame 150 in either the first orientation orthe second orientation, electrically couple the control unit 110 to thebattery 185. Alternatively, the control unit 110 may be configured toderive power from a power source connected to the mechanical switch 190,such as the source of AC power for example. Alternatively still, thecontrol unit 310 may be configured to house the battery 185.

In an example process of attaching the base 120 to the paddle actuator192 of the mechanical switch 190, the mounting tab 130 may be adhered tothe protruding portion of the paddle actuator 192 (e.g., the secondactuation surface 193 when the paddle actuator 192 is in the firstposition as shown) with the sheet 145 of double-sided adhesive. Theframe 150, with the attachment member 166 attached thereto, may then besecured to the mounting tab 130 by inserting the tab 168 into thechannel 134 of the mounting tab 130. As the tab 168 is received in thechannel 134, the rear surface 160 of the frame 150 may be biased againstthe outer surface 199 of the faceplate 196, for example as describedherein. With the base 120 attached to the paddle actuator 192 (e.g., asshown in FIG. 3), the control unit 110 may be attached to the base 120.

FIGS. 6-11 depict another example remote control device 200 that may beinstalled in a load control system, such as a lighting control system.The load control system may include a mechanical switch, such as themechanical switch 190, that may be in place prior to installation of theremote control device 200, for example pre-existing in the load controlsystem. The load control system may further include one or moreelectrical loads, such as lighting loads. The mechanical switch 190 maybe coupled in series electrical connection between an alternatingcurrent (AC) power source and the one or more electrical loads (notshown). The load control system may further include a load controldevice (not shown) that is electrically connected to the one or moreelectrical loads, as described herein.

As shown, the example remote control device 200 may include a controlunit 210 and a base 220 that may operate as a mount for the control unit210. The base 220 may alternatively be referred to as a base portion ora mounting assembly. The control unit 210 and the base 220 may beconfigured such that the control unit 210 may be removably attached tothe base 220. The base 220 may be attached to the paddle actuator 192 ofthe mechanical switch 190 without removing the faceplate 196. In thisregard, the remote control device 200 may be mounted over an installedmechanical switch, such as the mechanical switch 190, without performingany electrical re-wiring of the mechanical switch.

As shown, the base 220 may include a mounting tab 230 and a frame 250.The mounting tab 230 may be configured to be attached to the protrudingportion of the paddle actuator 192 of the mechanical switch 190. Forexample, as shown the mounting tab 230 may have a rectangular-shapedbody that defines an attachment surface 232 that is configured to beadhered to the protruding portion of the paddle actuator 192. Theattachment surface 232 may be adhered, for example, using double-sidedadhesive such as the illustrated sheet 245 of double-sided adhesive asshown in FIG. 7. The mounting tab 230 may be made of any suitablematerial, such as plastic. It should be appreciated that attachment ofthe mounting tab 230 to the paddle actuator 192 is not limited todouble-sided adhesive, and that the mounting tab 230 may bealternatively configured to otherwise attach to the protruding portionof the paddle actuator 192, for example mechanically (e.g., using one ormore fasteners).

As shown, the frame 250 may include an outer wall 252 that extends alonga perimeter of the frame 250. The outer wall 252 may alternatively bereferred to as a perimeter wall of the frame 250. The outer wall 252 mayinclude a first end wall 254, an opposed second end wall 256, andopposed side walls 258 that extend from respective ends of the first endwall 254 to corresponding ends of the second end wall 256. In accordancewith the illustrated orientation of the frame 250, the first end wall254 may be referred to as an upper end wall of the frame 250 and thesecond end wall 256 may be referred to as a lower end wall of the frame250. The outer wall 252 may define a rear surface 260 of the frame 250.

In accordance with the illustrated configuration of the frame 250, theframe 250 may be configured such that the outer wall 252 (e.g., at leasta portion of the rear surface 260 of the frame 250) abuts the bezel 194when the base 220 is attached to the protruding portion of the paddleactuator 192. It should be appreciated that the outer wall 252 of theframe 250 is not limited to the illustrated geometry. For example, theframe 250 may be alternatively configured such that the outer wall 252encloses the bezel 194 of the mechanical switch 190 and the rear surface260 of frame 250 abuts the outer surface 199 of the faceplate 196. Inanother example, the frame 250 may be alternatively configured such thatthe outer wall 252 encloses the faceplate 196 of the mechanical switch190, for instance such that the rear surface 260 of frame 250 abuts asurface of a structure in which the mechanical switch 190 is installed,such as a surface of a wall.

As shown, the frame 250 may be configured such that one or more outerperimeter surfaces of the outer wall 252 protrude beyond correspondingouter perimeter surfaces of the bezel 194 of the mechanical switch 190.It should be appreciated that the outer wall 252 of the frame 250 is notlimited to the illustrated geometry. For example, the frame 250 may bealternatively configured such that the outer perimeter surfaces of theouter wall 252 are flush with, or recessed relative to, correspondingouter perimeter surfaces of the bezel 194 of the mechanical switch 190.Such a configuration may allow the faceplate 196 of the mechanicalswitch 190 to be removed without detaching the frame 250 from the paddleactuator 192 of the mechanical switch 190.

The frame 250 may further include a cross member 262 that extendsbetween the opposed side walls 258 of the outer wall 252 (e.g., from afirst one of the side walls 258 to the other side wall 258). The frame250 may define an opening 264 that extends therethrough. The opening 264may be configured to receive the protruding portion of the paddleactuator 192 therein. When the protruding portion of the paddle actuator192 is received in the opening 264, the frame 250 may at least partiallysurround the paddle actuator 192 (e.g., as shown in FIG. 9). The frame250 may be made of any suitable material, such as plastic.

The base 220 may further include an attachment member 266 that may beconfigured to engage with the mounting tab 230 so as to secure the frame250 to the mounting tab 230. The attachment member 266 may include afirst portion 265 and a second portion 267 that defines a tab 268. Asshown, the tab 268 may extend outward from the first portion 265. Inthis regard, the attachment member 266 may extend from the frame 250.The attachment member 266 may be made of a suitably resilient material,such as metal.

The attachment member 266 may be configured to be translatable relativeto the frame 250. For example, as shown the attachment member 266 maydefine a slot 269 that extends therethrough. The slot 269 may extendfrom the first portion 265 into the second portion 267. The frame 250may be configured to captively support the attachment member 266 suchthat the attachment member 266 is translatable relative to the frame250. For example, as shown the cross member 262 may include a front wall261 and an opposed rear wall 263 that is spaced from the front wall 261.The front and rear walls 261, 263 may define a pocket 270 that isconfigured to receive the attachment member 266 therein. The firstportion 265 of the attachment member 266 may define a square shape thatmay be received in the pocket 270. The frame 250 may be configured tosupport the attachment member 266 such that the first portion 265 isfixed in position relative to the frame 250. The cross member 262 may beconfigured to captively retain the attachment member 266 such that theattachment member 266 is slidable within the pocket 270. For example, asshown each of the front and rear walls 261, 263 includes a post 272 thatextends inward into the pocket 270. The posts 272 may be configured tobe received in the slot 269 of the attachment member 266.

The posts 272 may operate as stops for sliding movement of theattachment member 266 in the pocket 270. For example, the attachmentmember 266 may be slid upwards toward the first end wall 254 until alower end of the slot 269 abuts the post 272 that extends from the rearwall 263 of the cross member 262. This position of the attachment member266, as shown in FIG. 8A, may be referred to a raised position of theattachment member 266. The attachment member 266 may be slid downwardtoward the second end wall 256 until an upper end of the slot 269 abutsthe post 272 that extends from the front wall 261 of the cross member262. This position of the attachment member 266, as shown in FIG. 8B,may be referred to a lowered position of the attachment member 266.

The mounting tab 230 may be configured to receive and captively retainthe attachment member 266. For example, as shown the mounting tab 230may define a channel 234 that is configured to receive the tab 268 ofthe attachment member 266 therein. The channel 234 may be recessed intoan outer surface 233 of the mounting tab 230. In accordance with theillustrated configuration of the mounting tab 230, the mounting tab 230may include a bridge 236 that extends across, and may define a portionof, the channel 234.

The base 220 may be configured to facilitate alignment of the frame 250relative to the mechanical switch 190, for instance during attachment ofthe base 220 to the paddle actuator 192 of the mechanical switch 190.For example, the base 220 may further include one or more alignmentmembers that may be configured to be received in the gap 197 between thebezel 194 of the mechanical switch 190 and the opening 198 of thefaceplate 196. The gap 197 may be defined as between the bezel 194 ofthe mechanical switch 190 that surrounds the paddle actuator 192 and theopening 198 that extends through the faceplate 196 that is attachable tothe yoke of the mechanical switch 190. The one or more alignment membersmay extend from the rear surface 260 of the frame 250. As shown, thebase 220 may include a plurality of alignment tabs 274 that may bereceived in slots (not shown) that extend into the rear surface 260 ofthe frame 250. When disposed in the respective slots of the frame 250,the alignment tabs 274 may extend outward from the rear surface 260 ofthe frame 250 such that the extending portions of the alignment tabs 274may be received in the gap 197.

The mounting tab 230 and the frame 250 may be configured to, when thebase 220 is attached to the paddle actuator 192 of the mechanical switch190, cause the rear surface 260 of the frame 250 to be biased against astructure that surrounds the paddle actuator 192, such as the bezel 194or the outer surface 199 of the faceplate 196. As shown (e.g., in FIG.8A), the tab 268 may extend from the first portion 265 of the attachmentmember 266 at a third angle α3 relative to the rear surface 260 of theframe 250. The third angle α3 may be smaller than the first angle α1formed by the second actuation surface 193 of the protruding portion ofthe paddle actuator 192 relative to the bezel 194 of the mechanicalswitch 190 (e.g., as shown in FIG. 7).

The mounting tab 230 may be configured such that when the tab 268 isdisposed into the channel 234 and under the bridge 236, the bridge 236may bias the tab 268 against the outer surface 233 of the mounting tab230. Accordingly, when the mounting tab 230 is attached to theprotruding portion of the paddle actuator 192 and the tab 268 isreceived in the channel 234, the tab 268 may deflect due to the sizedifference between the third angle α3 and the first angle α1. Thisdeflection of the tab 268 may cause the first portion 265 of theattachment member 266 to be biased rearward, thereby causing the rearsurface 260 of the frame 250 to be biased against the bezel 194 of themechanical switch 190. This may ensure uniform spacing between the rearsurface 260 of the frame 250 and the outer surface 199 of the faceplate196 (e.g., as shown in FIGS. 10B-10C).

The base 220 and the control unit 210 may be configured to enablereleasable attachment of the control unit 210 to the base 220. Forexample, one or more components of the base 220 may include engagementfeatures that may be configured to engage with complementary engagementfeatures of the control unit 210. As shown, the outer wall 252 of theframe 250 may define a plurality of recessed ledges 276 that may beconfigured to engage with corresponding resilient snap-fit connectors212 that extend rearward from the control unit 210. In this regard, theframe 250 may be configured for releasable attachment of the controlunit 210 to the frame 250, via the attachment member 266.

The control unit 210 may be configured to function similarly to thecontrol unit 110, but may omit the feature of pivoting about a centralaxis as included in the control unit 110. For example, the control unit210 may be configured to remain in a fixed position when attached to theframe 250, such that respective upper and lower portions 214, 216 of thecontrol unit 210 may not be actuated with presses. The control unit 210may define a control interface that is configured to receive inputs,such as gestures, from a user of the remote control device 200. Thecontrol unit 210 may define a capacitive touch surface along the upperand lower portions 214, 216, that may be configured to detect touchesalong an x axis, a y axis, or both an x and y axis.

The control unit 210 may be battery-powered. The frame 250 may beconfigured to receive a battery 185 (e.g., as shown in FIG. 11) forpowering the control unit 210. The base 220 may be configured to providepower from the battery 185 to the control unit 210 when the control unit210 is attached to the base 220. For example, the base 220 may include abattery PCB (not shown) that may be mounted to the frame 250, and thatmay operate similarly to the battery PCB 180 of the base 120 of theremote control device 100 to transfer power from the base 220 to thecontrol unit 210.

The control unit 210 may be configured such that power may betransferred from the battery 185 to the control unit 210 via the batteryPCB of the base 220. For example, the control unit 210 may include acontrol PCB (not shown) that may be configured similarly to the controlPCB 175 of the control unit 110. In this regard, the battery PCB of thebase 220 may be configured to, when the control unit 210 is attached tothe frame 250, electrically couple the control unit 210 to the battery185. Alternatively, the control unit 210 may be configured to derivepower from a power source connected to the mechanical switch 190, suchas the source of AC power for example. Alternatively still, the controlunit 210 may be configured to house the battery 185.

In an example process of attaching the base 220 to the paddle actuator192 of the mechanical switch 190, the mounting tab 230 may be adhered tothe protruding portion of the paddle actuator 192 (e.g., the secondactuation surface 193 when the paddle actuator 192 is in the firstposition as shown) with the sheet 245 of double-sided adhesive. Theframe 250, with the attachment member 266 captively disposed in thepocket 270, may then be secured to the mounting tab 230. For example,the attachment member 266 may be operated to the raised position, andthe frame 250 may be positioned against the bezel 194 of the mechanicalswitch 190 such that the alignment tabs 274 are received in the gap 197.With the frame 250 so positioned, the attachment member 266 may beoperated from the raised position to the lowered position, such that thetab 268 is disposed into the channel 234 of the mounting tab 230. As thetab 268 is received in the channel 234, the rear surface 260 of theframe 250 may be biased against the bezel 194 of the mechanical switch190, for example as described herein. With the base 220 attached to thepaddle actuator 192 (e.g., as shown in FIG. 9), the control unit 210 maybe attached to the base 220.

FIGS. 12-17 depict another example remote control device 300 that may beinstalled in a load control system, such as a lighting control system.The load control system may include a mechanical switch, such as themechanical switch 190, that may be in place prior to installation of theremote control device 300, for example pre-existing in the load controlsystem. The load control system may further include one or moreelectrical loads, such as lighting loads. The mechanical switch 190 maybe coupled in series electrical connection between an alternatingcurrent (AC) power source and the one or more electrical loads (notshown), such as a controllable light source. The load control system mayfurther include one or more load control devices (not shown) that areelectrically connected to the one or more electrical loads and/orintegral to the one or more electrical loads, as described herein.

As shown, the example remote control device 300 may include a controlunit 310 and a base 320 that may operate as a mount for the control unit310. The base 320 may alternatively be referred to as a base portion ora mounting assembly. The control unit 310 and the base 320 may beconfigured such that the control unit 310 may be removably attached tothe base 320. The base 320 may be attached to the paddle actuator 192 ofthe mechanical switch 190 without removing the faceplate 196. In thisregard, the remote control device 300 may be mounted over an installedmechanical switch, such as the mechanical switch 190, without performingany electrical re-wiring of the mechanical switch.

As shown, the base 320 may include a mounting tab 330 and a frame 350.The mounting tab 330 may be configured to be attached to the protrudingportion of the paddle actuator 192 of the mechanical switch 190. Forexample, as shown the mounting tab 330 may have a rectangular-shapedbody that defines an attachment surface 332 that is configured to beadhered to the protruding portion of the paddle actuator 192. Theattachment surface 332 may be adhered, for example, using double-sidedadhesive such as the illustrated sheet 345 of double-sided adhesive asshown in FIG. 13. The mounting tab 330 may be made of any suitablematerial, such as plastic. It should be appreciated that attachment ofthe mounting tab 330 to the paddle actuator 192 is not limited todouble-sided adhesive, and that the mounting tab 330 may bealternatively configured to otherwise attach to the protruding portionof the paddle actuator 192, for example mechanically (e.g., using one ormore fasteners).

As shown, the frame 350 may include an outer wall 352 that extends alonga perimeter of the frame 350. The outer wall 352 may alternatively bereferred to as a perimeter wall of the frame 350. The outer wall 352 mayinclude a first end wall 354, an opposed second end wall 356, andopposed side walls 358 that extend from respective ends of the first endwall 354 to corresponding ends of the second end wall 356. In accordancewith the illustrated orientation of the frame 350, the first end wall354 may be referred to as an upper end wall of the frame 350 and thesecond end wall 356 may be referred to as a lower end wall of the frame350. The outer wall 352 may define a rear surface 360 of the frame 350.

In accordance with the illustrated configuration of the frame 350, theframe 350 may be configured such that the outer wall 352 (e.g., at leasta portion of the rear surface 360 of the frame 350) abuts the bezel 194when the base 320 is attached to the protruding portion of the paddleactuator 192. It should be appreciated that the outer wall 352 of theframe 350 is not limited to the illustrated geometry. For example, theframe 350 may be alternatively configured such that the outer wall 352encloses the bezel 194 of the mechanical switch 190 and the rear surface360 of frame 350 abuts the outer surface 199 of the faceplate 196. Inanother example, the frame 350 may be alternatively configured such thatthe outer wall 352 encloses the faceplate 196 of the mechanical switch190, for instance such that the rear surface 360 of frame 350 abuts asurface of a structure in which the mechanical switch 190 is installed,such as a surface of a wall.

As shown, the frame 350 may be configured such that one or more outerperimeter surfaces of the outer wall 352 protrude beyond correspondingouter perimeter surfaces of the bezel 194 of the mechanical switch 190.It should be appreciated that the outer wall 352 of the frame 350 is notlimited to the illustrated geometry. For example, the frame 350 may bealternatively configured such that the outer perimeter surfaces of theouter wall 352 are flush with, or recessed relative to, correspondingouter perimeter surfaces of the bezel 194 of the mechanical switch 190.Such a configuration may allow the faceplate 196 of the mechanicalswitch 190 to be removed without detaching the frame 350 from the paddleactuator 192 of the mechanical switch 190.

The mounting tab 330 may be monolithic with the frame 350. For example,as shown the frame 350 may further include a cross member 362 thatextends between the opposed side walls 358 of the outer wall 352 (e.g.,from a first one of the side walls 358 to the other side wall 358). Asshown, the mounting tab 330 may extend outward from the cross member 362such that the attachment surface 332 of the mounting tab 330 isangularly offset relative to the rear surface 360 of the frame 350. Themounting tab 330 may define a fixed end 334 where the mounting tab 330extends from the cross member 362, and a free end 336 that is spacedfrom the fixed end 334. In this regard, as shown the mounting tab 330may extend outward from the fixed end 334, which may be supported by theframe 350, to the free end 336.

The frame 350 may define an opening 364 that extends therethrough. Theopening 364 may be configured to receive the protruding portion of thepaddle actuator 192 therein. When the protruding portion of the paddleactuator 192 is received in the opening 364, the frame 350 may at leastpartially surround the paddle actuator 192 (e.g., as shown in FIG. 15).The frame 350 may be made of any suitable material, such as plastic.

The base 320 may be configured to facilitate alignment of the frame 350relative to the mechanical switch 190, for instance during attachment ofthe base 320 to the paddle actuator 192 of the mechanical switch 190.For example, the base 320 may further include one or more alignmentmembers that may be configured to be received in the gap 197 between thebezel 194 of the mechanical switch 190 and the opening 198 of thefaceplate 196. As shown, the frame 350 may include a plurality ofalignment ridges 366 that may extend outward from the rear surface 360of the frame 350 such that the alignment ridges 366 may be received inthe gap 197. The frame 350 may be configured such that the alignmentridges 366 engage with corresponding outer surfaces of the bezel 194 ofthe mechanical switch 190. It should be appreciated that the alignmentridges 366 are optional and may be omitted from an exampleimplementation of the frame 350.

The mounting tab 330 and the frame 350 may be configured to, when thebase 320 is attached to the paddle actuator 192 of the mechanical switch190, cause the rear surface 360 of the frame 350 to be biased against astructure that surrounds the paddle actuator 192, such as the bezel 194or the outer surface 199 of the faceplate 196. As shown (e.g., in FIG.13), the mounting tab 330 may extend from the frame 350 at the fourthangle α4 relative to the rear surface 360 of the frame 350. For example,the attachment surface 332 may form the fourth angle α4 relative to therear surface 360 of the frame 350. The fourth angle α4 may be smallerthan the first angle α1 formed by the second actuation surface 193 ofthe protruding portion of the paddle actuator 192 relative to the bezel194 of the mechanical switch 190 (e.g., as shown in FIG. 13).

When the mounting tab 330 is attached to the protruding portion of thepaddle actuator 192 of the mechanical switch 190, the mounting tab 330may deflect, for example may bend near or at the fixed end 334, due tothe size difference between the fourth angle α4 and the first angle α1.This deflection of the mounting tab 330 may cause the cross member 362,and thus the frame 350, to be biased rearward, thereby causing the rearsurface 360 of the frame 350 to be biased against the bezel 194 of themechanical switch 190. This may ensure uniform spacing between the rearsurface 360 of the frame 350 and the outer surface 199 of the faceplate196.

The base 320 may be configured to enable releasable attachment of thecontrol unit 310 to the base 320. For example, one or more components ofthe base 320 may include engagement features (not shown) that may beconfigured to engage with complementary engagement features (not shown)of the control unit 310. In this regard, the frame 350 may be configuredfor releasable attachment of the control unit 310 to the frame 350.

The control unit 310 may be configured to function similarly to thecontrol unit 110. For example, the control unit 310 may define a controlinterface that is configured to receive inputs, such as finger pressesand/or gestures, from a user of the remote control device 300. Forexample, in accordance with the illustrated configuration, the controlunit 310 may be configured to pivot about a central axis, when attachedto the base 320, in response to actuations of respective upper and lowerportions 312, 314 of the control unit 310. The control unit 310 mayfurther define a capacitive touch surface along the upper and lowerportions 312, 314, that may be configured to detect touches along an xaxis, a y axis, or both an x and y axis.

The control unit 310 may be battery-powered. The frame 350 may beconfigured to receive a battery (not shown) for powering the controlunit 310. The base 320 may be configured to provide power from thebattery to the control unit 310 when the control unit 310 is attached tothe base 320. For example, the base 320 may include a battery PCB (notshown) that may be mounted to the frame 350, and that may operatesimilarly to the battery PCB 180 of the base 120 of the remote controldevice 100 to transfer power from the base 320 to the control unit 310.

The control unit 310 may be configured such that power may betransferred from the battery to the control unit 310 via the battery PCBof the base 320. For example, the control unit 310 may include a controlPCB (not shown) that may be configured similarly to the control PCB 175of the control unit 110. In this regard, the battery PCB of the base 320may be configured to, when the control unit 310 is attached to the frame350, electrically couple the control unit 310 to the battery.Alternatively, the control unit 310 may be configured to derive powerfrom a power source connected to the mechanical switch 190, such as thesource of AC power for example. Alternatively still, the control unit310 may be configured to house the battery.

In an example process of attaching the base 320 to the paddle actuator192 of the mechanical switch 190, the frame 350 may be aligned with thebezel 194 of the mechanical switch 190 such that the alignment ridges366, if present, are received in the gap 197. The mounting tab 330 maythen be adhered to the protruding portion of the paddle actuator 192(e.g., the second actuation surface 193 when the paddle actuator 192 isin the first position as shown) with the sheet 345 of double-sidedadhesive. As the mounting tab 330 is adhered to the protruding portionof the paddle actuator 192, the rear surface 360 of the frame 350 may bebiased against the bezel 194 of the mechanical switch 190. With the base320 attached to the paddle actuator 192 (e.g., as shown in FIG. 15), thecontrol unit 310 may be attached to the base 320.

FIGS. 18-22 depict another base 420 that may be implemented in theremote control device 300, for example in the place of the base 320. Thebase 420 may be attached to the paddle actuator 192 of the mechanicalswitch 190 without removing the faceplate 196. In this regard, theremote control device 300 may be mounted over an installed mechanicalswitch, such as the mechanical switch 190, without performing anyelectrical re-wiring of the mechanical switch.

As shown, the base 420 may include a mounting tab 430 and a frame 450.The mounting tab 430 may be configured to be attached to the protrudingportion of the paddle actuator 192 of the mechanical switch 190. Forexample, as shown the mounting tab 430 may define an attachment surface432 that is configured to be adhered to the protruding portion of thepaddle actuator 192. The attachment surface 432 may be adhered, forexample, using double-sided adhesive such as the illustrated sheet 445of double-sided adhesive as shown in FIG. 18. The mounting tab 430 maybe made of any suitable material, such as plastic. It should beappreciated that attachment of the mounting tab 430 to the paddleactuator 192 is not limited to double-sided adhesive, and that themounting tab 430 may be alternatively configured to otherwise attach tothe protruding portion of the paddle actuator 192, for examplemechanically (e.g., using one or more fasteners).

As shown, the frame 450 may include an outer wall 452 that extends alonga perimeter of the frame 450. The outer wall 452 may alternatively bereferred to as a perimeter wall of the frame 450. The outer wall 452 mayinclude a first end wall 454, an opposed second end wall 456, andopposed side walls 458 that extend from respective ends of the first endwall 454 to corresponding ends of the second end wall 456. In accordancewith the illustrated orientation of the frame 450, the first end wall454 may be referred to as an upper end wall of the frame 450 and thesecond end wall 456 may be referred to as a lower end wall of the frame450. The outer wall 452 may define a rear surface 460 of the frame 450.

In accordance with the illustrated configuration of the frame 450, theframe 450 may be configured such that the outer wall 452 (e.g., at leasta portion of the rear surface 460 of the frame 450) abuts the bezel 194when the base 420 is attached to the protruding portion of the paddleactuator 192. It should be appreciated that the outer wall 452 of theframe 450 is not limited to the illustrated geometry. For example, theframe 450 may be alternatively configured such that the outer wall 452encloses the bezel 194 of the mechanical switch 190 and the rear surface460 of frame 450 abuts the outer surface 199 of the faceplate 196. Inanother example, the frame 450 may be alternatively configured such thatthe outer wall 452 encloses the faceplate 196 of the mechanical switch190, for instance such that the rear surface 460 of frame 450 abuts asurface of a structure in which the mechanical switch 190 is installed,such as a surface of a wall.

As shown, the frame 450 may be configured such that one or more outerperimeter surfaces of the outer wall 452 protrude beyond correspondingouter perimeter surfaces of the bezel 194 of the mechanical switch 190.It should be appreciated that the outer wall 452 of the frame 450 is notlimited to the illustrated geometry. For example, the frame 450 may bealternatively configured such that the outer perimeter surfaces of theouter wall 452 are flush with, or recessed relative to, correspondingouter perimeter surfaces of the bezel 194 of the mechanical switch 190.Such a configuration may allow the faceplate 196 of the mechanicalswitch 190 to be removed without detaching the frame 450 from the paddleactuator 192 of the mechanical switch 190.

The mounting tab 430 may be monolithic with the frame 450. For example,as shown the frame 450 may further include a cross member 462 thatextends between the opposed side walls 458 of the outer wall 452 (e.g.,from a first one of the side walls 458 to the other side wall 458). Asshown, the mounting tab 430 may extend outward from the cross member 462such that the attachment surface 432 of the mounting tab 430 isangularly offset relative to the rear surface 460 of the frame 450. Themounting tab 430 may define a fixed end 434 where the mounting tab 430extends from the cross member 462, and a free end 436 that is spacedfrom the fixed end 434. In this regard, as shown the mounting tab 430may extend outward from the fixed end 434, which may be supported by theframe 450, to the free end 436.

The mounting tab 430 may have a wedge-shaped body that tapers withincreasing distance from the fixed end 434. As shown, the body of themounting tab 430 may be configured to maximize thickness of the mountingtab 430 along a direction that extends perpendicular to the outersurface 199 of the faceplate 196. This configuration may in turnmaximize stiffness of the mounting tab 430 while maintaining clearancefor the mounting of a control unit (e.g., the control unit 310) to thebase 420. The mounting tab 430 may be configured to reduce the effectsof peel loading that may, for example, potentially cause thedouble-sided adhesive to peel away from the second actuation surface 193of the paddle actuator 192 over time. The body of the mounting tab 430may define an arm 438 that extends from the fixed end 434 to anintermediate joint 440, such that the mounting tab 430 defines aU-shaped attachment surface 432. As shown, the arm 438 may be centeredbetween opposed sides of the mounting tab 430, and may have a lengthsuch that the intermediate joint 440 is spaced approximatelyequidistantly from opposed upper and lower edges of the mounting tab430.

The frame 450 may define an opening 464 that extends therethrough. Theopening 464 may be configured to receive the protruding portion of thepaddle actuator 192 therein. When the protruding portion of the paddleactuator 192 is received in the opening 464, the frame 450 may at leastpartially surround the paddle actuator 192 (e.g., as shown in FIG. 20).The frame 450 may be made of any suitable material, such as plastic.

The base 420 may be configured to facilitate alignment of the frame 450relative to the mechanical switch 190, for instance during attachment ofthe base 420 to the paddle actuator 192 of the mechanical switch 190.For example, the base 420 may further include one or more alignmentmembers that may be configured to be received in the gap 197 between thebezel 194 of the mechanical switch 190 and the opening 198 of thefaceplate 196. As shown, the frame 450 may include a plurality ofalignment ridges 466 that may extend outward from the rear surface 460of the frame 450 such that the alignment ridges 466 may be received inthe gap 197. The frame 450 may be configured such that the alignmentridges 466 engage with corresponding outer surfaces of the bezel 194 ofthe mechanical switch 190. It should be appreciated that the alignmentridges 466 are optional and may be omitted from an exampleimplementation of the frame 450.

The mounting tab 430 and the frame 450 may be configured to, when thebase 420 is attached to the paddle actuator 192 of the mechanical switch190, cause the rear surface 460 of the frame 450 to be biased against astructure that surrounds the paddle actuator 192, such as the bezel 194or the outer surface 199 of the faceplate 196. As shown (e.g., in FIG.18), the mounting tab 430 may extend from the frame 450 at a fifth angleα5 relative to the rear surface 460 of the frame 450. The fifth angle α5may be smaller than the first angle α1 formed by the second actuationsurface 193 of the protruding portion of the paddle actuator 192relative to the bezel 194 of the mechanical switch 190 (e.g., as shownin FIG. 18).

When the mounting tab 430 is attached to the protruding portion of thepaddle actuator 192 of the mechanical switch 190, one or more portionsof the mounting tab 430 may deflect, for example may bend near or at thefixed end 434 and/or near or at the intermediate joint 440, due to thesize difference between the fifth angle α4 and the first angle α1. Thisdeflection of the mounting tab 430 may cause the cross member 462, andthus the frame 450, to be biased rearward, thereby causing the rearsurface 460 of the frame 450 to be biased against the bezel 194 of themechanical switch 190. This may ensure uniform spacing between the rearsurface 460 of the frame 450 and the outer surface 199 of the faceplate196.

The base 420 may be configured to enable releasable attachment of thecontrol unit 310 to the base 420. For example, one or more components ofthe base 420 may include engagement features (not shown) that may beconfigured to engage with complementary engagement features (not shown)of the control unit 310. In this regard, the frame 450 may be configuredfor releasable attachment of the control unit 310 to the frame 450.

The frame 450 may be configured to receive a battery (not shown) forpowering the control unit 310. The base 420 may be configured to providepower from the battery to the control unit 310 when the control unit 310is attached to the base 420. For example, the base 420 may include abattery PCB (not shown) that may be mounted to the frame 450, and thatmay operate similarly to the battery PCB 180 of the base 120 of theremote control device 100 to transfer power from the base 420 to thecontrol unit 310. The battery PCB of the base 420 may be configured to,when the control unit 310 is attached to the frame 450, electricallycouple the control unit 310 to the battery.

In an example process of attaching the base 420 to the paddle actuator192 of the mechanical switch 190, the frame 450 may be aligned with thebezel 194 of the mechanical switch 190 such that the alignment ridges466, if present, are received in the gap 197. The mounting tab 430 maythen be adhered to the protruding portion of the paddle actuator 192(e.g., the second actuation surface 193 when the paddle actuator 192 isin the first position as shown) with the sheet 445 of double-sidedadhesive. As the mounting tab 430 is adhered to the protruding portionof the paddle actuator 192, the rear surface 460 of the frame 450 may bebiased against the bezel 194 of the mechanical switch 190. With the base420 attached to the paddle actuator 192 (e.g., as shown in FIG. 20), thecontrol unit 310 may be attached to the base 420.

FIGS. 23-27 depict another base 520 that may be implemented in theremote control device 300, for example in the place of the base 320. Thebase 520 may be attached to the paddle actuator 192 of the mechanicalswitch 190 without removing the faceplate 196. In this regard, theremote control device 300 may be mounted over an installed mechanicalswitch, such as the mechanical switch 190, without performing anyelectrical re-wiring of the mechanical switch.

As shown, the base 520 may include a mounting tab 530 and a frame 550.The mounting tab 530 may be configured to be attached to the protrudingportion of the paddle actuator 192 of the mechanical switch 190. Forexample, as shown the mounting tab 530 may define an attachment surface532 that is configured to be adhered to the protruding portion of thepaddle actuator 192. The attachment surface 532 may be adhered, forexample, using double-sided adhesive such as the illustrated sheet 545of double-sided adhesive as shown in FIG. 23. The mounting tab 530 maybe made of any suitable material, such as plastic. It should beappreciated that attachment of the mounting tab 530 to the paddleactuator 192 is not limited to double-sided adhesive, and that themounting tab 530 may be alternatively configured to otherwise attach tothe protruding portion of the paddle actuator 192, for examplemechanically (e.g., using one or more fasteners).

As shown, the frame 550 may include an outer wall 552 that extends alonga perimeter of the frame 550. The outer wall 552 may alternatively bereferred to as a perimeter wall of the frame 550. The outer wall 552 mayinclude a first end wall 554, an opposed second end wall 556, andopposed side walls 558 that extend from respective ends of the first endwall 554 to corresponding ends of the second end wall 556. In accordancewith the illustrated orientation of the frame 550, the first end wall554 may be referred to as an upper end wall of the frame 550 and thesecond end wall 556 may be referred to as a lower end wall of the frame550. The outer wall 552 may define a rear surface 560 of the frame 550.

In accordance with the illustrated configuration of the frame 550, theframe 550 may be configured such that the outer wall 552 (e.g., at leasta portion of the rear surface 560 of the frame 550) abuts the bezel 194when the base 520 is attached to the protruding portion of the paddleactuator 192. It should be appreciated that the outer wall 552 of theframe 550 is not limited to the illustrated geometry. For example, theframe 550 may be alternatively configured such that the outer wall 552encloses the bezel 194 of the mechanical switch 190 and the rear surface560 of frame 550 abuts the outer surface 199 of the faceplate 196. Inanother example, the frame 550 may be alternatively configured such thatthe outer wall 552 encloses the faceplate 196 of the mechanical switch190, for instance such that the rear surface 560 of frame 550 abuts asurface of a structure in which the mechanical switch 190 is installed,such as a surface of a wall.

As shown, the frame 550 may be configured such that one or more outerperimeter surfaces of the outer wall 552 protrude beyond correspondingouter perimeter surfaces of the bezel 194 of the mechanical switch 190.It should be appreciated that the outer wall 552 of the frame 550 is notlimited to the illustrated geometry.

The mounting tab 530 may be monolithic with the frame 550. For example,as shown the frame 550 may further include a cross member 562 thatextends between the opposed side walls 558 of the outer wall 552 (e.g.,from a first one of the side walls 558 to the other side wall 558). Asshown, the mounting tab 530 may extend outward from the cross member 562such that the attachment surface 532 of the mounting tab 530 isangularly offset relative to the rear surface 560 of the frame 550. Themounting tab 530 may define a fixed end 534 where the mounting tab 530extends from the cross member 562, and a free end 536 that is spacedfrom the fixed end 534. In this regard, as shown the mounting tab 530may extend outward from the fixed end 534, which may be supported by theframe 550, to the free end 536.

The mounting tab 530 may have a wedge-shaped body that tapers withincreasing distance from the fixed end 534. As shown, the body of themounting tab 530 may be configured to maximize thickness of the mountingtab 530 along a direction that extends perpendicular to the outersurface 199 of the faceplate 196. This configuration may in turnmaximize stiffness of the mounting tab 530 while maintaining clearancefor the mounting of a control unit (e.g., the control unit 310) to thebase 520. The mounting tab 530 may be configured to reduce the effectsof peel loading that may, for example, potentially cause thedouble-sided adhesive to peel away from the second actuation surface 193of the paddle actuator 192 over time. The body of the mounting tab 530may define a pair of arms 538 that extend from the fixed end 434 torespective intermediate joints 540, such that the mounting tab 530defines a T-shaped attachment surface 532. As shown, the arms 538 may bespaced apart from each other, for example at opposed sides of themounting tab 530, and may have respective lengths such that theintermediate joints 540 are spaced approximately equidistantly fromopposed upper and lower edges of the mounting tab 530. Thisconfiguration of the arms 538 may enhance lateral stability of the base520, for example by minimizing movement of the frame 550 (e.g., alongdirections parallel to the rear surface 560 of the frame 550) when thebase 520 is attached to the protruding portion of the paddle actuator192, while maximizing available surface area for the sheet 545 ofdouble-sided adhesive.

The frame 550 may define an opening 564 that extends therethrough. Theopening 564 may be configured to receive the protruding portion of thepaddle actuator 192 therein. When the protruding portion of the paddleactuator 192 is received in the opening 564, the frame 550 may at leastpartially surround the paddle actuator 192 (e.g., as shown in FIG. 25).The frame 550 may be made of any suitable material, such as plastic.

As shown (e.g., in FIG.23), the mounting tab 530 may extend from the frame 550 at a sixth angleα6 relative to the rear surface 560 of the frame 550. The sixth angle α6may be smaller than the first angle α1 formed by the second actuationsurface 193 of the protruding portion of the paddle actuator 192relative to the bezel 194 of the mechanical switch 190 (e.g., as shownin FIG. 23).

When the mounting tab 530 is attached to the protruding portion of thepaddle actuator 192 of the mechanical switch 190, one or more portionsof the mounting tab 530 may deflect, for example may bend near or at thefixed end 534 and/or near or at the intermediate joints 540, due to thesize difference between the fifth angle α4 and the first angle α1.

For example, one or more components ofthe base 520 may include engagement features (not shown) that may beconfigured to engage with complementary engagement features (not shown)of the control unit 310. In this regard, the frame 550 may be configuredfor releasable attachment of the control unit 310 to the frame 550.

The frame 550 may be configured to receive a battery (not shown) forpowering the control unit 310. The base 520 may be configured to providepower from the battery to the control unit 310 when the control unit 310is attached to the base 520.

With the base520 attached to the paddle actuator 192 (e.g., as shown in FIG. 25), thecontrol unit 310 may be attached to the base 520.

FIGS. 28-31 depict another base 620 that may be implemented in theremote control device 300, for example, in the place of the base 320.The base 620 may be attached to the paddle actuator 192 of themechanical switch 190 without removing the faceplate 196. In thisregard, the remote control device 300 may be mounted over an installedmechanical switch, such as the mechanical switch 190, without performingany electrical re-wiring of the mechanical switch.

The base 620 may include a plurality of mounting teeth 630 and a frame650, for example, as shown. The frame 650 may be made of any suitablematerial, such as plastic. The mounting teeth 630 may be configured tosecure the frame 650 onto the protruding portion of the paddle actuator192. Each of the plurality of mounting teeth 630 may be a thin piece ofmetal that is cantilevered from the frame 650. Each of the plurality ofmounting teeth 630 may have a rectangular shape. The mounting teeth 630may be arranged along opposed sides of an opening 664 that extendsthrough the frame 650. The mounting teeth 630 may be evenly spaced alongthe opposed sides of the opening 664. The opening 664 may be configuredto receive the protruding portion of the paddle actuator 192 therein.When the protruding portion of the paddle actuator 192 is received inthe opening 664, the frame 650 may at least partially surround thepaddle actuator 192 (e.g., as shown in FIG. 30). The mounting teeth 630may be configured to be attached to the protruding portion of the paddleactuator 192 of the mechanical switch 190. For example, the mountingteeth 630 may engage opposed walls of the protruding portion of thepaddle actuator 192 of the mechanical switch 190. The mounting teeth 630may be compliant such that the mounting teeth 630 are configured to bendas they engage the opposed walls of the protruding portion of the paddleactuator 192 of the mechanical switch. The mounting teeth 630 may applya force against (e.g., bite into) the opposed walls of the protrudingportion of the paddle actuator 192 of the mechanical switch.

The frame 650 may include an outer wall 652 that extends along aperimeter of the frame 650, for example, as shown. The outer wall 652may alternatively be referred to as a perimeter wall of the frame 650.The outer wall 652 may include a first end wall 654, an opposed secondend wall 656, and opposed side walls 658 that extend from respectiveends of the first end wall 654 to corresponding ends of the second endwall 656. In accordance with the illustrated orientation of the frame650, the first end wall 654 may be referred to as an upper end wall ofthe frame 650 and the second end wall 656 may be referred to as a lowerend wall of the frame 650. The outer wall 652 may define a rear surface660 of the frame 650. The mounting teeth 630 may be configured todeflect (e.g., bend) near or at the opposed side walls 658.

The frame 650 may be configured such that the outer wall 652 (e.g., atleast a portion of the rear surface 660 of the frame 650) abuts thebezel 194 when the base 620 is attached to the protruding portion of thepaddle actuator 192, for example, as illustrated. It should beappreciated that the outer wall 652 of the frame 650 is not limited tothe illustrated geometry. For example, the frame 650 may be configuredsuch that the outer wall 652 encloses the bezel 194 of the mechanicalswitch 190 and the rear surface 660 of frame 650 abuts the outer surface199 of the faceplate 196. In another example, the frame 650 may beconfigured such that the outer wall 652 encloses the faceplate 196 ofthe mechanical switch 190, for instance such that the rear surface 660of frame 650 abuts a surface of a structure in which the mechanicalswitch 190 is installed, such as a surface of a wall.

The frame 650 may be configured such that one or more outer perimetersurfaces of the outer wall 652 protrude beyond corresponding outerperimeter surfaces of the bezel 194 of the mechanical switch 190, forexample, as shown. It should be appreciated that the outer wall 652 ofthe frame 650 is not limited to the illustrated geometry. For example,the frame 650 may be configured such that the outer perimeter surfacesof the outer wall 652 are flush with, or recessed relative to,corresponding outer perimeter surfaces of the bezel 194 of themechanical switch 190. Such a configuration may allow the faceplate 196of the mechanical switch 190 to be removed without detaching the frame650 from the paddle actuator 192 of the mechanical switch 190.

The frame 650 may further include a cross member 662 that extendsbetween the opposed side walls 658 of the outer wall 652 (e.g., from afirst one of the side walls 658 to the other side wall 658). The crossmember 662 may be configured to provide structural support to the base620.

The base 620 may be configured to facilitate alignment of the frame 650relative to the mechanical switch 190, for instance during attachment ofthe base 620 to the paddle actuator 192 of the mechanical switch 190.For example, the base 620 may further include one or more alignmentmembers (not shown) that may be configured to be received in the gap 197between the bezel 194 of the mechanical switch 190 and the opening 198of the faceplate 196.

In an example process of attaching the base 620 to the paddle actuator192 of the mechanical switch 190, the frame 650 may be aligned with thebezel 194 of the mechanical switch 190, for example such that alignmentfeatures of the frame 650 are received in the gap 197. The mountingteeth 630 may then be secured to the protruding portion of the paddleactuator 192 (e.g., the second actuation surface 193 when the paddleactuator 192 is in the first position as shown) by applying a force onthe base 620 in the direction of the mechanical switch 190. As themounting teeth 630 are secured to the protruding portion of the paddleactuator 192, the rear surface 660 of the frame 650 may be biasedagainst the bezel 194 of the mechanical switch 190. With the base 620attached to the paddle actuator 192 (e.g., as shown in FIG. 30), thecontrol unit 310 may be attached to the base 620.

FIG. 32 depicts an example remote control device 700 (e.g., such as theremote control devices 100, 200, and/or 300) having an alternate controlunit 710. The example remote control device 700 may include a controlunit 710 and a base 720 that may operate as a mount for the control unit710, for example, as shown. The base 720 may alternatively be referredto as a base portion or a mounting assembly. The control unit 710 andthe base 720 may be configured such that the control unit 710 may beremovably attached to the base 720. The base 120 may be attached to apaddle actuator (e.g., such as paddle actuator 192 shown in FIG. 2A) ofa mechanical switch (e.g., the mechanical switch 190 shown in FIG. 2A)without removing the faceplate 196. In this regard, the remote controldevice 700 may be mounted over an installed mechanical switch, such asthe mechanical switch 190, without performing any electrical re-wiringof the mechanical switch, as described herein.

The control unit 710 may define a control interface that is configuredto receive inputs, such as finger presses and/or gestures, from a userof the remote control device 700. For example, in accordance with theillustrated configuration, the control unit 710 may define a capacitivetouch surface 712 that may be configured to detect touches along an xaxis, a y axis (e.g., as shown in FIG. 32), or both an x and y axis.

It should be appreciated that the bases 120, 220, 320, 420, 520, and 620are not limited to the respective configurations illustrated anddescribed herein, and that respective components of the bases mayalternatively be configured with other suitable geometries. For example,the respective frames 150, 250, 350, 450, 550, and 650 of the bases 120,220, 320, 420, 520, and 620, may be alternatively configured such thattheir outer walls bound greater or lesser areas. To illustrate, theouter walls of one or more of the frames 150, 250, 350, 450, 550, and650 may be configured to bound an area that is smaller than thefootprint of the paddle actuator 192 of the mechanical switch 190, whichmay allow the faceplate 196 to be removed without disturbing the frameor necessitating its detachment from the paddle actuator 192.Additionally, it should be appreciated that the respective mounting tabsof the bases 120, 220, 320, 420, 520, and 620 are not limited to therespective configurations illustrated and described herein, and mayalternatively be configured with other suitable geometries, for instanceto define alternative attachment surfaces.

It should further be appreciated that one or more of the frames 150,250, 350, 450, 550, and 650 may be alternatively configured to allowreleasable attachment of control units having geometries different fromthose of the illustrated control units. To illustrate, one or more ofthe frames 150, 250, 350, 450, 550, and 650 may be alternativelyconfigured to allow releasable attachment of control units havingrespective footprints (e.g., areas) that are larger than thecorresponding footprints of the frames, for instance such that thecontrol units enclose the frames and/or at least partially hide theframes from view. Additionally, one or more of the frames 150, 250, 350,450, 550, and 650 may be alternatively configured to allow releasableattachment of control units other than the illustrated control units110, 210, 310, and 710 such as control units having different geometriesand/or defining other types of user interfaces, for example.

It should further still be appreciated that configuring the base of aremote control device such that the frame of the base biases against thebezel of a mechanical switch to which the base is mounted (e.g., inaccordance with the bases 220, 320, 420, 520, and 620 illustrated anddescribed herein) may provide one or more advantages. For example, soconfiguring the base may limit or reduce the need to account forvariables in one or more of the lateral (e.g., side-to-side),longitudinal (e.g., upward and downward), and transverse (e.g., along adirection perpendicular to the outer surface of the faceplate) that maybe exhibited by the respective dimensions or geometries (e.g., paddleheights) of different mechanical switches and/or installation conditionsof the mechanical switches. Additionally, so referencing the base to thebezel of the mechanical switch, for instance rather than to the outersurface of the faceplate, may eliminate the need to account for theframe enclosing the bezel of the mechanical switch, since bezeldimensions may vary from switch to switch.

It should further still be appreciated that any of the example remotecontrol devices 100, 200, 300, and 700 illustrated and described hereinmay provide a simple retrofit solution for an existing switched controlsystem, and may ease the installation of a load control system orenhance an existing load control system installation. A load controlsystem that integrates one of the remote control devices 100, 200, 300,or 700 may provide energy savings and/or advanced control features, forexample without requiring any electrical re-wiring and/or withoutrequiring the replacement of any existing mechanical switches.

It should further still be appreciated that load control systems intowhich the example remote control devices 100, 200, 300, and/or 700 maybe integrated are not limited to the example load control devices and/orelectrical loads described above. For example, load control systems intowhich the remote control devices 100, 200, 300, and/or 700 may beintegrated may include one or more of: a dimming ballast for driving agas-discharge lamp; a light-emitting diode (LED) driver for driving anLED light source; a dimming circuit for controlling the intensity of alighting load; a screw-in luminaire including a dimmer circuit and anincandescent or halogen lamp; a screw-in luminaire including a ballastand a compact fluorescent lamp; a screw-in luminaire including an LEDdriver and an LED light source; an electronic switch, controllablecircuit breaker, or other switching device for turning an appliance onand off; a plug-in load control device, controllable electricalreceptacle, or controllable power strip for controlling one or moreplug-in loads; a motor control unit for controlling a motor load, suchas a ceiling fan or an exhaust fan; a drive unit for controlling amotorized window treatment or a projection screen; one or more motorizedinterior and/or exterior shutters; a thermostat for a heating and/orcooling system; a temperature control device for controlling a setpointtemperature of a heating, ventilation, and air-conditioning (HVAC)system; an air conditioner; a compressor; an electric baseboard heatercontroller; a controllable damper; a variable air volume controller; afresh air intake controller; a ventilation controller; hydraulic valvesfor use in one or more radiators of a radiant heating system; a humiditycontrol unit; a humidifier; a dehumidifier; a water heater; a boilercontroller; a pool pump; a refrigerator; a freezer; a television and/orcomputer monitor; a video camera; an audio system or amplifier; anelevator; a power supply; a generator; an electric charger, such as anelectric vehicle charger; an alternative energy controller; and thelike.
